New Technologies Clean Water Treatment with catalysts.Recently, Hitachi's research team announced that they had found a new technology in water treatment. They have succeeded in developing catalyst technology to describe organic substances contained in water. The catalyst used is an active catalyst when subjected to ultraviolet light. It is said that more than 90 percent of organic matter including Dioxins can be described this way.

The advantages of this technology compared to existing technology for this is to simply use the catalyst without the use of additives. The cost of this process is much cheaper than existing technology today, for example, than by using the membrane. In addition, decomposition of organic matter with this technology requires a relatively short time.

The downside of this technology is the threshold concentration of pollutants that are still relatively small, under 100 ppm. Thus, for waste water which has a high concentration of organic substances is very high preliminary process is required to reduce the content of organic substances.

Catalysts are substances that can accelerate or stimulate the occurrence of a reaction. In this case the reaction of organic matter decomposition. For this water treatment process, the catalyst used was Titan Oxide. Titan Oxide became stronger after oxidizing ultraviolet light illuminated. Titan has an active oxide will oxidize organic substances there.

Water purifier designed by Hitachi has a simple form. Namely in the form of a cylindrical reactor with a source of ultraviolet light in the middle. Meanwhile, the catalyst attached to the cylinder wall with adhesives. Waste water is passed to the reactor cylinder and organic substances contained in them will be described by the catalyst in the cylinder wall. Currently, Indonesia is facing serious problems of clean water. It seems that we can put hope in the development of this technology.
